Kai knew kissing Baekhyun’s girlfriend that one time during the Yule ball was going to backfire on him bad, considering that said girlfriend was also Chanyeol’s sister, which made it double-bad (Chanyeol had cornered him after and demanded he pay for stealing his sister’s virtue); what he didn’t expect was for Baekhyun to hunt him down and spend the rest of his life at Hogwarts making Kai’s life miserable whenever they were in the same room.
